INFICON 074-494-P10E Pilot Plus Vacuum Gauge
The Pilot Plus is a digital gauge designed to accurately measure vacuum levels
during evacuation of HVAC/R systems from atmosphere down to 1 micron (0.001
Torr,
0.01 mbar, 1 Pa) using INFICON’s proprietary “Pirani” sensor, the most
accurate vacuum sensor in its class.
Operating Instructions
- Remove the battery cover and install the 9-volt battery. An indicator shows when the battery needs to be replaced.
- Connect a dedicated or new charging hose to the Pilot Plus fitting.
- a. A previously used hose may contain oil that could affect the sensor performance.
- b. Normal refrigeration hoses outgas (leak) which may make it difficult to measure below 250 microns. We suggest using a metal braided hose for better accuracy.
- c. We recommend using a hose no longer than 3 feet. A longer hose may make the gauge unable to read lower vacuum levels due to excessive outgassing.
- Connect the other end of the hose directly to either the high or low side of the system for most accurate readings. You can also connect the hose to one of the ports on the vacuum pump itself. To connect the gauge in-line with a manifold set or the vacuum pump, you will need a separate 1/4″ male by 1/4 ” male by 1/4″ female T fitting.
- Turn the Pilot Plus on by pressing the On/Off button. Readings greater than 1500 are displayed as 3 digits followed by the X1000 indicator. For example, a reading of 100,000 is displayed as 100 X1000.
- The Pilot Plus automatically turns off after 1 hour when the vacuum reading is above 30,000 microns. The last reading before auto shutdown and MEMORY are displayed for 5 seconds when the unit is turned back on. Auto shut-down is disabled when the vacuum level is below 30,000 microns. However, you can turn the Pilot Plus off or on at any pressure.
Vacuum Units Selection
The Pilot Plus can display vacuum in units of Torr, microns, mbar or Pascal. To change units, press and hold the power button for 3 seconds during power-up and the indicator for the active units flashes. Briefly press the power button again to select the desired units. Press and hold the power button for 1 second to save the setting.
Quick Calibration
The Pilot Plus has a quick calibration feature to allow for equalization to different atmospheric pressures. Press CAL to activate. CAL flashes on the display and the reading stabilizes at 760 x 1000. The gauge will maintain this reference point until a new one is set. Note: quick calibration is disabled at vacuum levels below 100,000 microns.
Changing The Filter
The Pilot Plus is equipped with a special filter to protect the vacuum sensor
from oil and other contaminants. To change the filter, remove the setscrew in
the unit’s fitting. See Figure 1. Use an 11/ 16″ wrench to stabilize the top
portion of the fitting. Then twist off the lower portion of the fitting using
a 1/2″ wrench. Use needle-nose pliers or a similar item to gently pull out the
used filter. Do not attempt to clean or re-use filters. Insert a new filter
with the thicker portion of the o-ring facing away from the gauge’s body. Re-
attach the refrigerant flare. Tighten the fitting with the wrenches and
replace the set screw to ensure vacuum integrity.
